Geum Plant Named &#39;MACGEU004&#39;

ABSTRACT

‘MACGEU004’ is a new and distinctive variety of  Geum  hybrid plant which is characterized by a large plant size, large dark green leaves, and tall inflorescences bearing large orange-red flowers. The new variety propagates successfully by stem cuttings and tissue culture and has shown to be uniform and stable in the resulting generations from asexual propagation.

CROSS REFERENCE TO RELATED APPLICATIONS

This application claims priority to the Community Plant Variety Rightsapplication number 2019/2733, filed Oct. 28, 2019, which is hereinincorporated by reference.

Latin name of the genus and species: The Latin name of the genus andspecies of the novel variety disclosed herein is Geum hybrid.

Variety denomination: The inventive variety of Geum hybrid disclosedherein has been given the variety denomination ‘MACGEU004’.

BACKGROUND OF THE INVENTION

Parentage: ‘MACGEU004’ is the result of a controlled cross-pollinationbreeding program carried out by the inventors at their commercialnursery in Kirkcudbright, Scotland, in June of 2010. The inventorsperformed a controlled cross-pollination of the emasculated seed parent,Geum chiloense ‘Red Dragon’ (unpatented), with an unnamed Geum hybridplant (unpatented), the pollen parent. Said pollination was performed inan insect proof environment. Seed from said cross was harvested, thengerminated, and the resulting seedlings were then grown to a mature sizein a protected poly tunnel greenhouse. In June of 2012, the inventorsselected the new Geum cultivar for its unique flower and bloomcharacteristics. This new and distinctive cultivar was given the name‘MACGEU004’.

Asexual Reproduction: Asexual reproduction of ‘MACGEU004’ was firstaccomplished in June of 2012 by way of vegetative division andsubsequently by way of meristematic tissue culture micro propagation ata laboratory in Rijswijk, the Netherlands. Successive generations haveshown that the unique features of the instant cultivar are stable andreproduce true to type.

SUMMARY OF THE INVENTION

The cultivar ‘MACGEU004’ has not been observed under all possibleenvironmental conditions and the phenotype may vary somewhat withvariations in the instant environment such as temperature, day length,and light intensity, without, however, any variance in genotype. Thefollowing traits have been repeatedly observed and represent thedistinguishing characteristics of the new Geum cultivar, ‘MACGEU004’.

1. Geum ‘MACGEU004’ exhibits a large plant size; and

2. Geum ‘MACGEU004’ exhibits large, dark green foliage; and

3. Geum ‘MACGEU004’ exhibits cyme inflorescences borne on longpeduncles; and

-   -   4. Geum ‘MACGEU004’ exhibits large orange-red semi-double        flowers.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinctvariety of Geum known as ‘MACGEU004’, based upon observations of 4.5month old plants grown outdoors in Kirkcudbright, Scotland. Plants weregrown with full sun to partial shade exposure and subsisted on naturalrainfall with supplemental irrigation provided during periods of dryweather. Plants were grown in a nutrient-rich compost but were otherwisenot given any supplemental fertilizer. No chemical pest treatments weregiven to the plants. Observation data was recorded in May of 2020.

Those skilled in the art will appreciate that certain characteristicswill vary with older or, conversely, with younger plants. ‘MACGEU004’has not been observed under all possible environmental conditions. Wheredimensions, sizes, colors and other characteristics are given, it is tobe understood that such measurements are approximations or averages setforth as accurately as practicable. The phenotype of the variety maydiffer from the descriptions set forth herein with variations inenvironmental, climactic and cultural conditions. Color notations arebased on The Royal Horticultural Society Colour Chart, The RoyalHorticultural Society, London, 2007 edition.
